Application filed May 18, 1918. Serial No; 235,295.

To all whom it may concern.-

Be it known that I, Ci-IAnLEsSL Runs, a citizen of the UnitedStates,residing at San Antonio, in the county of Bexar and State ofTexas, have invented certain new and useful Improvements inLens-Mountings, of which the following is a specification, referencebeing had to the accompanying drawings. p

This invention relates to certain improvements in lens mounting and hasrelation more particularly to a mounting especially designed and adaptedfor use in rimless eyeglasses and it is an object of the invention toprovide a mounting having novel and improved means whereby the lens ismaterially relieved from the effects of a jar or strain which wouldotherwise lnve a tendency to break the lens.

It is also an object of the invention to provide a novel and improvedmounting of this general character including a strap having its marginalportions defined by inwardly directed brace or flanges: whereby thestrap has a rigid and non-yielding formation and wherein the boX likestructure is produced in which a marginal portion of a lens is seated.

A still further object of the invention is to provide a novel andimproved mounting embodying a strap having its marginal portions definedby inwardly directed flanges for maintaining a strap against flexure andwherein said flanges are adapted for connection with a marginal portionof a lens inserted therebetween together with a cushioning elementinterposed between the inner face of the strap proper and the adjacentedge of a lens to serve as a means to substantially absorb the effectsof a jar or strain and which also serve to prevent the strap from beingdrawn too tight on the lens in fitting and thereby obviating thepossibility of the lens being cracked or otherwise broken.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my im proved lensmounting whereby certain important advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand advantageous for use as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In orderthat my invention may be the better understood, I will nowproceed to de ings 1 denotes a strap of predetermined length andconfiguration and which is adapted to overliean edge of a lens L at anend thereof andthe longitudinal marginal portions of said strap aredefined by inwardly directed flanges 2 which serve as braces whereby thestrap 1 is held against flexure and thereby maintained rigid and at alltimes in its fixed formation so that when the mounting is applied to thelens L the strap is incapable of bending so that the possibility of thelens L becoming loosened is substantially entirely GllllllILtltGCla Theflanges 2 at substantially their longitudinal centers are provided withthe transversely alined and inwardly directed ears 3 each of whichhaving an opening 4- alining with the opening 5 produced in the marginalportion of the lens L. Disposed through the registering openings 4: and5 is a fastening screw 6 whereby the mounting or strap is held to thelens L. The perforations 4 are so positioned relative to the strap 1 asto permit the strap to have slight limited movement about the screw 6relative to the marginal portion of the lens. Suitably secured to theinner face of the strap 1 is a strip 7 of rubber or other elasticmaterial and which bears directly upon the marginal portion of the lens.

The strip 7 acts as a cushioning element and serves to cause the strap 1to fit firmly and rigidly to the lens without causing any strain on thelens and to absorb any shock or sudden jar. It has been fullydemonstrated in practice that the cushioning element as afforded by thestrip 7 serves effectively to prevent breakage or cracking of Myimproved mounting as hereinbefore Specification of Letters Patent.Patented Mfal'. 23, 1920.

' described permits the lens to be readily interchangeable without theservices of a skilled Workman. 7

It has also been firmly established in actual practice that with amounting constructed in accordance with an embodiment of my inventionthe possibility of the lens becoming loose is substantially entirelyeliminated and which advantageous funcloose. c

From ,the foregoing description, it is thought to be obvious that a lensmounting constructed in accordance with my lnvention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be assembled and operated and it will also be obvious thatmy invention is susceptible of some change and modification Withoutdeparting from the principles and spirit thereof and for this reason Ido not a wish tozbe understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim:

As a new article of manufacture, a mounting for a rimless lens of aneyeglass, a strap disposed longitudinally on a curvature to conform toan edge portion of the lens, the longitudinal marginal portions oi. thestrap being defined throughout their length by inwardly directed flangesserving as braces to render said strap unbendable, said flanges midwaytheir lengths being provided with transversely alined and inwardlydirected ears, a holding member disposed through said ears and the lens,said holding member serving as a pivot to permit the strap to have aslight limited movement relative to the marginal portion of the lens,and a strip of elastic material secured to the inner face of the strapand extending the entire length thereof, said strip being constantly incontact with an edge portion of the lens.

In testimony whereof I hereunto afiix my signature.

CHARLES S. REES.
